This is an unfinished sketch of a scene in the control room of a sinking submarine. Although I drew this maybe four years ago, I think I was doing this for some kind of contest I was trying to win. On the top of the drawing are a few stylized three-dimensional stage lights. I draw these in as ruffs when I want to render light sources into my artwork, either manually or by using a computer. That way, I will understand where the specular highlights and thrown shadows will fall.
